Plasma sustainment by Neutral Beam Injection: from current leading experiments to future nuclear fusion reactors.
Vincenzi P., Bolzonella T., Vallar M.
A possible way to exploit nuclear fusion for electricity production is the magnetic confinement of hot plasmas. Temperatures of several keV are required to reach ignition, and additional heating systems, such as neutral beam injection (NBI), are employed to heat and sustain the plasma. NBI can also act as direct actuator for plasma kinetic and current profile control, resulting a crucial actor for reaching reactor parameters. In this work, simulations of the interaction between NBI and plasma are presented, both for current leading fusion experiments and for predictions of future reactors performance.
